Application filed July 10, 1890. Serial No. 358,263. (No model.)

To all whom it may concern.-

Be it known that We, JOHN C. LOWDON, of Kansas City, in the county ofJackson and State of Missouri, and J AMES DIXON, of Kansas City, in thecounty of IVyandotte and State of Kansas, have invented certain new anduseful Improvements in Smoke-Consumers,.of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

Our invention relates to an improved smoke-consumer to be used inconnection with locomotive and other furnaces; and our inventionconsists in features of novelty here;

inafter described, and pointed out in the claim.

FigureI is a longitudinal section of a locomotive with our improvementattached. Fig. II is a perspective of our improved deflector. Figlll isan enlarged detail front View of the furnace-door. Fig.1" is atransverse section show-in g exhaust-nozzle.

Referring to the drawings, 1 represents a locomotive-boiler with theusual fire-tubes 2.

3 represents the fire-chamber of the locomotive, having a deflector-arch4.

5 represents our improved concave deflector for assisting in retardingthe smoke and gases until they have been consumed. The deflector isprovided with corrugations 6 to add to its strength, and is set in thefront wall of the fire-chamber just over an opening 7 through whichfresh air is admitted to the furnace. The deflector extendsinwardly anddownwardly to about the center of the firechamber. The deflector 5 andarch 4E retard the smoke and gases in the fire-chamber until the majorportion of the same has been consumed, the heat taking the course shownby arrows, Fig. I.

8 represents a door by which the opening 7 may be closed, if desired;but it is intended for this door to remain open the most of the time inorder to supply plenty of fresh air to the furnace or fire-chamber.

9 represents a door, to which the smaller door 8 is hinged, said largerdoor having suitable hinges and latch, as shown at 10 11.

12 represents the latch of the door 8, to which is secured a chain 13for operating the same.

14 represents the smoke-stack, in which there is a central tube or pipe15.

16 represents a nozzle, through which the exhaust-steam may pass fromthecylinders 17 out through said nozzle and the tube 15 in order toincrease the draft.

18 represents a vertically'movable sleeve situated on the nozzle 16 nearits upper end. By raising orlowering said sleeve on the nozzle the draftmay be increased or diminished by permitting a greater or less amount ofthe products of combustion to pass off through the tube 15. (See dot-tedlines, Fig. I.)

19 represents a set-screw for holding the sleeve 18 at any desiredpoint.

e claim as our invention The combination of the boiler l, fines 2,fire-chamber 3, deflector 5, deflecting-arch l, doors 8 9, suitablehinges and fastenings on said doors, smoke-stack 14, flue 15 in theSmokestack, exhaust-nozzle 1G, and adjustable sleeve 18 on said nozzle,substantially as described, and for the purpose set forth.
